A GtkShortcutsSection collects all the keyboard shortcuts and gestures for a major application mode.
If your application needs multiple sections, you should give each section a unique section_name and a title that can be shown in the section selector of the GtkShortcutsWindow.
The max_height property can be used to influence how the groups in the section are distributed over pages and columns.
This widget is only meant to be used with ShortcutsWindow.
